For now, we can’t get a definite answer. We can model with an equation, but we cannot find the absolute amount Jocelyn will earn, as her hourly rates are both variables. All we must do to create an equation for this is multiply the amount of hours by the rate and add. You could model like this:
25n + 15x = total amount earned
Answer:
Step-by-step explanation:
let : x and t this numbers : x +y = -81/4
y == -52/3
x + (-52/3) = -81/4
x = -81/4 + 52/3........continue
The area of the green region is of:
9 units².
<h3>How to obtain the area of the green region?</h3>
The base is composed by three equal segments, hence their lengths are given as follows:
AB = BC = CD = 9/3 = 3.
The heights are given as follows:
As they are proportional.
The green region is composed by:
- A rectangle of dimensions 3 and 2.
- A right triangle of sides 3 and 2.
The area of the rectangle is given by the multiplication of the dimensions, hence:
Ar = 3 x 2 = 6 units².
The area of the triangle is given by half the multiplication of the dimensions, hence:
At = 0.5 x 3 x 2 = 3 units².
Then the area of the green region is given by:
A = Ar + At = 6 + 3 = 9 units².

Answer:
the cost is 
Step-by-step explanation:
observing the graph
we know that
For the interval of x------>
-----> the cost is 
For the interval of x------>
-----> the cost is 
For the interval of x------>
-----> the cost is 
For the interval of x------>
-----> the cost is 
In this problem we have
hours and
minutes
therefore
the value of x belong to the interval ![(3,4]](https://tex.z-dn.net/?f=%283%2C4%5D)
the cost is
